Abstract
A method of improving the mechanical properties of polymers is described. The method involves heat treating the polymer at a temperature below the glass transition temperature in a wet or in a dry environment. Polymer articles capable of moisture uptake in humid environments, as well as polymer articles less susceptible to moisture uptake, have improved mechanical properties, particularly improved stress relaxation behavior and set properties, when treated in accord with the heat treatment method.
